You forgot to mention pricey Oink. It is nice though.
I think everyone else is right though, you really want Eldar terrain you might as well make it yourself. Making webways and pylons from foamcore isn't that tough, and the Planetstrike rulebook has an example of an Eldar bastion made out of a 2 liter soda bottle, some wood accents (purchased at most major wood supply or hardware stores) and random Eldar vehicle bits.
